@Just BobI think Mr. Burdette, excuse me, Mr. Roger, is talking to you. LOL
Well I may be wrong, but, as a fellow Mississippian, I think @Just Bob probably said Mr. Burdette out of sheer habit (and, of course, utmost respect). I say sir, ma'am, Mr, Ms, to EVERYONE. Younger and older.
1. It just sounds better.
2. My momma would have gotten me good if I hadn't, (and still would) ... so it is a habit.
3. I will get mine good if they don't, so I make sure to keep it a habit so they will.
4. The lessons taught were that it ain't gonna hurt you to say it whether they are younger or older, but if you don't say it and should've then you are gonna get hurt for sure! Do it is best just to say it.
And that, folks, is our Sweet Southern Tea lesson for today. π
